Troubleshooting Guide
Trouble Probable Cause Solution
No power
Fuse Disconnect Power Cord. Replace fuse.
Power Switch
Disconnect Power Cord. Use ohmmeter
to check yellow and black leads at Switch.
Reading should be 0 to full scale when
switched from on to o.
Power Cord
Use Voltmeter to check white lead at
terminal block and black lead at Switch.
Reading should be 115V AC.
Transformer
Use Voltmeter to check the two yellow leads
from the Transformer. Reading should be
24V AC.
Circuit Board Replace the Circuit Board.
